Keyboard shortcuts allow users to move through Ribbon tabs, items, and drop-down menus and execute any command. Keyboard navigation is implemented on the client and works seamlessly even in Blazor Server apps with a slow connection.
Note
Keyboard support allows users to interact with application content in cases they cannot use a mouse or they rely on assistive technologies (like screen readers or switch devices). Refer to the Accessibility help topic for information on other accessibility areas that we address.
